The LMV3xxA-Q1 family includes single (LMV321A-Q1), dual (LMV358A-Q1), and quad-channel (LMV324A-Q1) low-voltage (2.5 V to 5.5 V) automotive operational amplifiers (op amps) with rail-to-rail output swing capabilities. These op amps provide a cost-effective method for space-constrained applications such as infotainment and lighting where low-voltage operation and high capacitive-load drive are required. The capacitive-load drive of the LMV3xxA-Q1 family is 500 pF, and the resistive open-loop output impedance makes stabilization easier with much higher capacitive loads. These op amps are designed specifically for low-voltage operation (2.5 V to 5.5 V) with performance specifications similar to the LMV3xx-Q1 devices.

The robust design of the LMV3xxA-Q1 family simplifies circuit design. The op amps feature unity-gain stability, an integrated RFI and EMI rejection filter, and no-phase reversal in overdrive conditions.

The LMV3xxA-Q1 family is available in industry-standard packages such as SOIC, MSOP, SOT-23, and TSSOP packages.

CIRCUIT060074 — 具有比較器電路的高壓側電流感測

此高壓側電流感測解決方案使用一個具有軌對軌輸入共模範圍的比較器，若負載電流上升到 1 A 以上，便在比較器輸出 (COMP OUT) 建立過電流警示 (OC 警示) 訊號。此實作中的 OC 訊號為低電位作動。因此當超過 1-A 閾值時，比較器輸出會變低。實作磁滯後會在負載電流降低至 0.5 A (減少 50%) 時，讓 OC-Alert 返回邏輯高狀態。此電路利用開漏輸出比較器，為控制數位邏輯輸入針腳而進行電平轉換輸出高邏輯電平。對於需要驅動 MOSFET 開關閘極的應用，建議使用具推挽輸出的比較器。
